Is it a UTI or a year infection?

So my vag has been itching lately, nothing too unbearable. I have no irregular discharge and now stinging sensation when I pee. It smells normal.... it just itches. It’s not dry. When I give into the urge to scratch it kind of burns and when I wipe after peeing it kinda burns. I put some Monistat cream on it but idk what else to do bc it still itches and I wanna have goodbye sex tomorrow and I don’t think I can do that with an itchy vag. What should I do?
